Log in to the official platform you are using** and select your province to inquire.

Users can query their current traffic usage anytime and anywhere in the mobile phone business hall, and also support SMS reminders for traffic usage on a daily, weekly, and monthly basis.

Save data. Many friends have been complaining that their mobile phone data is not enough, which has something to do with the way they use their mobile phones.

If your phone has a Wi-Fi function, try to use Wi-Fi where it is available.

If you can turn off the animation sound when browsing the web, turn it off as much as possible, and upload it after you try to compress it as little as possible.

Always check the background program of the network, and if you can set the interval between the software to connect to the Internet, you can set it as large as possible (e.g., check the time of email). Disable functions such as automatic software update and automatic network information acquisition.

Use a data-saving browser to turn on compression relay, low color and other functions.

The cost-effective mobile phone cards are as follows:

1. Bilibili.

It is a flow-free card designed for the Bilibili APP platform, which is convenient for mobile phone users who use the Bilibili APP to provide smooth movies, resources, and 1GB of national traffic.

2. China Merchants Bank mobile phone card is a new mobile phone activity launched by China Merchants Bank and China Unicom, including large and small cards, focusing on traffic and calls.

3. The tariff of the big card is 96 yuan per month, 6GB domestic traffic, 600 minutes of domestic calls, free caller ID, no roaming charges, and 10 GB automatic renewal of domestic traffic.

4. The tariff of the small card is 36 yuan per month, 2GB domestic traffic, 100 minutes of domestic calls, free caller ID, no roaming charges, and 10 GB automatic renewal of domestic traffic.

The King Card is not bad.

The use of IM card completely prevents parallel and call eavesdropping, and the production of SIM card is done in strict accordance with international standards and specifications, which makes the normal communication of customers be reliably guaranteed.

If you don't have a SIM card installed, you can only call numbers such as this one. The application of SIM card in the system separates the card from the mobile phone, and a SIM card uniquely identifies a customer. A SIM card can be inserted into any mobile phone and used.

A SIM card is a smart card containing a microprocessor, which consists of five parts: CPU (8 bits), RAM (working memory, 6 16 KB), ROM (program memory, 3 8 KB), EPROM or EEPROM (data memory, 128 256 KB), and serial communication unit.

These five modules are integrated in an integrated circuit to prevent unauthorized access and theft, as the connection between the chips can be an important clue to illegal access and theft of SIM cards.

When the SIM card is connected to the mobile phone, it needs to have at least five connections, as shown in Figure 1. In the figure, VCC is the power supply, CLK is the clock, RESET is the reset and unused, GND is the ground terminal, I O is the data input and output interface, and VPP is the programming voltage.

First of all, don't touch the traffic card, I just bought the traffic card for a month before, and I ran away, I still wonder why the customer service ignores me, and I see that the products in the store are gone, it's disgusting, **Regardless of this? The first time I used this kind of traffic card, is this a common routine? Asked about Telecom.,Telecom said that the 105 phone bill is going to find the merchant.,Damn,The merchant ran away directly.,Where else can I find it.。。。

It's the first time I've used this kind of traffic card, it's disgusting.

The communication industry has been very deep, especially in the category of mobile phone cards, although there are broken card actions, but due to the low entry threshold of the mobile phone card industry, low-quality first-class businessmen continue, the Internet is full of false and exaggerated publicity, operators continue to take off the shelves, and many low-cost mobile phone cards are restricted from the promotion channels.

The mobile phone card in the treasure traffic card that I have been using has a call and SMS function, and the traffic is not empty. Share it, and if you need it, you can see if there is anything suitable for you. **There are also quite a lot of treasure flow cards - **complete - can be claimed for free.
